ELECTRIC PACK.

Specification of Letters Patent.

Patented Nov. '7, 1916.

Application filed March 17, 1914. Serial No. 825,360.

To all whom it may concern:

Be it known that I, HENRY PERLMAN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in ElectricPacks, of'which'the following is a specification.

My invention relates to new and useful improvements in electric packs,and has for its object to construct a device of this character in suchmanner that the distance between the sides may be varied considerablywithout materially reducing the height.

Another object of the invention is to provide an electric packcomprising a body having side members hinged thereto in such a mannerthat the side members may be adjusted to vary the distance therebetweenwithout materially changing the distance between the body, and the lowerends of the side members.

A further object of the invention is to provide an electric packconsisting of a body or crown having a side section or member hinged toeach end thereof so that said side sections may be adjusted withrelation to each other to vary the space between them without materiallyreducing the space between the body or crown, and the object on whichthe device is resting and without changing the contour of the body orcrown section.

A still further object of the invention is to provide a body or crownhaving sides adjustably attached thereto whereby the inclosed space maybe varied without changing the contour of the body.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by I the claims.

In carrying out my invention as here embodied 2 represents the body orcrown of the electric pack which is arcuate in shape or curvedlongitudinally and comprises a pair of arcuate or bowed ribs or flanges3, spaced apart and held in their relative positions by the cross pieces4, the ends of the latter beng bent at right angles and secured to theinner faces of theflanges adjacent the ends thereof by any suitablemeans such as screws 5 and a cover or roof 6, curved in cross section,the opposite edges of which are fastened to the cross pieces 4 as byscrews 7. The roof, 6 preferably consists of a sheet of asbestos 8underlying a protecting and stiifenmg wall 9 of metal. The body or crowncarries a handle '10 secured thereto in any suitable and well knownmanner.

The sides are designated by the numeral 11 and are constructed in thesame manner as the body or crown 2, each comprising the flanges 3, thecross pieces 4 and cover or roof 6. v

To each end of the body or crown 2 is hinged or otherwise adjustablyattached a side member 11 by any suitable and well known means hereshown as comprising bolts"- 12 or their equivalent which pass throughthe overlapping flanges of the body and side members and have nuts 13,preferably of the butterfly type, threaded on their outer ends.

After the side members have been adjusted the nuts 13 are jammed againstthe outer flanges to hold said side members in their adjusted positions.

In the inner faces of the flanges 3 are mounted a number of electriclamp sockets 14 which are connected with each other and with a conductorcord 15 by means of wires 16, said wires and cord having a suitableswitch 17 interposed therebetween so that the electrical current 'may beturned on or oil"; The sockets are preferably wired in serieswhereby theelectrical current may be turned into all or a certain number of thesockets.

In the sockets 14 are placed the electric lamps 18 which when the deviceis in use, and the electrical current is turned on, will generatesufficient heat to bake a portion of a patients body for relieving orcuring certain bodily diseases.

By constructing an electric pack in accordance with my improvements itis possible to vary the distance between the side members withoutmaterially changing the position of the body and without changing thecontour of said body, which is impossible with bakers that are made ofonly one or two.

members. I

Of course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be varied within the limits ofthe appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and usefulis .1 In a device of the character stated an arcuate body comprising apair of arcuate flanges, cross pieces for spacing said flanges andholding them in their relative positions, an inclosing wall, theopposite edges of which are secured to the cross pieces, sockets mountedon the 'inner'faces of the flanges, electric lamps mounted in saidsockets, a pair of side members, each comprising a pair of flanges,cross pieces secured to said flanges adjacent their ends and aninclosing wall, the edges of which are secured to said cross pieces,sockets mounted on the inner faces of said flanges, electric lampsmounted in said sockets, means for hingedly connecting the side pieceswith the ends of the body,

wires connecting the different sockets, a conductor cord connected withsaid wires and a switch interposed between said wires and the conductorcord.

2. An electric pack comprising an arched body or crown, side membershingedly connected to the ends of said body and means carried by thebody and side members for heating the interior thereof.

3. An electric pack comprising an arcuate or arched body or crown, apair of oppo- ',-sitely disposed arcuate side members hingedly securedto said body or crown, means for hinging said side members to the bodycrown and means for heating the interior thereof.

4. An electric pack comprising an arcuate or arched body or crown, anarcuate side member hinged to each end of said body, said side membersbeing adjustable toward or away from each other to vary the distancetherebetween, means for holding said side members in their adjustedpositions and means carried by the body and side members for heating theinterior thereof.

5. An electric pack comprising three arcuate members hinged together,whereby the central member becomes the crown of the arch formed by saidmembers, said crown member being so arranged with relation to the othermembers as to form a solid wall between said members, and electric lightbulbscarried by said members for heating the interior thereof.

In testimony whereof, I have hereunto affixed my signature'in thepresence of two subscribing witnesses.
